How to Choose the Wire Liner for Direct and Euro Connection Torches
• There are basically 2 types of wire liners: Steel wire liners and Teflon wire liners.
• Steel wire liners can be coated or not coated. Coated wire liners are used for air cooled
torches. The wire liners are used for water cooled torches.
• Teflon wire liners are recommended for aluminum welding as they allow a smooth feeding of
the wire.
Arrangement for Welding with Spool Gun
WARNING: Electric shock can kill! Always turn the POWER switch OFF and unplug the
power cord from the AC power source before installing wire.
Before installing any welding wire into the unit,
the proper sized groove must be placed into
position on the wire drive mechanism. Adjust the
drive roller according to the following steps:
1. Open the wire drive cover on the spool gun.
2. Remove the drive tension by loosening the
tension adjusting screw and lifting the drive
tension adjustor up, away from the drive tension
arm. Pull the drive tension arm away from the drive roller.
3. Rotate the drive roller cap counterclockwise and remove it from the drive wire drive cover
drive roller cap FIG. 7 tension adjusting screw drive tension arm roller. Pull the drive roller off
of the drive roller shaft . Note: The drive roller has two wire size (.030", .035") grooves built
into it.
4. Find the side of the drive roller that is stamped with the same wire diameter as that of the wire
being installed. Push the drive roller onto the drive roller shaft, with the side stamped with the
desired wire diameter facing you.
5. Reinstall the drive roller cap and lock in place by turning it clockwise.
6. Remove the nozzle and contact tip from the end of the gun assembly.
7. Open the wire spool casing, located at the rear of the spool gun, by turning the retaining
knob counterclockwise.
8. Unwrap the spool of wire and find the end of the wire.
9. After checking to make sure that your welder is disconnected from the AC power source, free
the leading end of the wire from the spool, but do not let go of it until told to do so, or the
wire will unspool itself.
10. Using a wire cutter, cut off the bent portion at the end of the wire so that you are left with a
straight section of wire.
11. Unroll about 6" of welding wire from the wire spool.
12. Insert the leading end of the wire into the inlet guide tube (located in the Wire Spool Casing).
Then push it across the drive roller and into the gun assembly about 6".
13. Line the wire up in the appropriate top groove of the drive roller, then push the drive tension
arm against the drive roller.
